===MTF "Reverse Kettle Sour"===
Devin Bell has experienced getting good sourness by co-pitching probiotics with ''L. plantarum'' with yeast, or even after primary fermentation (also known as the "Reverse MTF Sour"). In the case of pitching ''L. plantarum'' after fermentation, the beer turned out like a sour saison, where as co-pitched makes for a better Berliner Weisse or Gose style beer. This has also improved head retention in his beers. Using no hops seems to be required in order to get acid production from the ''L. plantarum'' probiotics after primary fermentation. Devin clarified that his "best success" is pitching ''S. cerevisiae'' saison strain with a selection of ''Brettanomyces'' for primary fermentation. After 5-7 days of fermentation, he pitches ''L. plantarum'' (GoodBelly or Omega Labs OYL-605). Once terminal gravity is reached (1.002-1.004), he bottles right away. The bottles can be served at 8 weeks in the bottle, but start to peak at 24 weeks. This process is really more of a short term [[Mixed Fermentation]] <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1562696320425243/?comment_id=1562702310424644&comment_tracking=%7B%22tn%22%3A%22R0%22%7D MTF discussion with Devin Bell on "reverse MTF kettle sour. 01/26/2017.]</ref>.
